RAZOR BLADE SHARPENER Filed Aug. 6, 1964 United States Patent 3,266,198RAZOR BLADE SHARPENER Bernard M. Schramko, RD. 4, Quaker-town, Pa. FiledAug. 6, 1964, Ser. No. 387,836 8 Claims. (Cl. 51-158) This inventionrelates to sharpening devices and more particularly to an apparatus forresharpening or honing razor blades and the like.

It is an object of the present invention to provide a razor bladesharpener which will allow the user to obtain higher efiicien-cy fromhis razor blades, enabling the blade to be used for a longer period oftime.

Another object of the present invention is to provide a razor bladesharpener which will be battery powered or electrically powered by motormeans which will oscillate an arm to secure a razor blade within a tankof water or other solution to hone the razor blade to a fine edge.

A further object of the present invention is to provide a razor bladesharpener which will have a curved glass plate submerged beneath theliquid in order to hone the razor blade which will be held by suctioncup or other suitable means to the arm.

A still further object of the present invention is to provide a razorblade sharpener which will have magnetic plate means secured to thecontainer to securely hold the device upon a metal surface.

Other objects of the invention are to provide a razor blade sharpenerbearing the above objects in mind which will be of simple construction,have a minimum number of parts, be inexpensive to manufacture andeflicient in operation and use.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconjunction with the accompanying drawing, in which:

FIGURE 1 is a side view of the present invention shown in section and inelevation;

FIGURE 2 is a viewv taken along the lines 2-2 of FIGURE 1;

FIGURE 3 is a schematic wiring diagram of the invention; and

FIGURE 4 is a side view of one of the glass holddown spring clips of theinvention.

Referring now more in detail to the drawing, a razor blade sharpenermade in accordance with the present invention is shown to include ahollow, rectangular tank 12 made of metal or other suitable materialwhich contains a quantity of water, or oil, or the like. The water 14 orother solution contained within container 12 provides a means ofproducing a fine edge on a razor blade. A magnet plate 16 of rectangularconfiguration is fixedly secured to the lower extremity of container 12and provides a means of securing razor blade sharpener 10 to a metallicsurface in order to prevent it from moving. A metallic plate 18 isreceived within container 12 and is secured in an angular position to anend wall and to the base wall of the interior of container 12 andprovides support means when arcuately curved glass 20 is springinglyheld and urged against plate 18 by means of a pair of spring clamps 22which are fixedly secured to the side wall of container 12. A housing 24is fixedly secured to an end wall of container 12 and receives a pair ofbatteries 26 which provide a means for driving motor 28 which is inseries with a switch 30. Switch 30 provides a means for shutting razorblade sharpener 10 on or oil as desired. An arm 32 pivotably securedwithin housing 24 is provided with a pair of spaced apart suction cups34 which engage by differential in pressure a surface of razor blade 36which is moved in a hori- 3,26%,l98 Patented August 16, 1966 zontaldirection across the surface of glass 20 to hone the edges of razorblade 36. A leaf spring 38 is fixedly secured at one end to the upperextremity of housing 24 and springingly urges against the lowerextremity of arm 32 at its other end to provide the necessary pressureon razor blade 36 to effect a proper honing action within water 14.

In use, arm 32 is lifted from Within water 14 and razor blade 36 isurged against suction cups 34 to hold razor blade 36 to arm 32. Arm 32is then released in order that razor blade 36 may be submerged by thespring .action of leaf spring 38. Switch 30 .is then turned to the onposition and by conventional means arm 32 oscillates to sharpen razorblade 36 by means of glass 20 within water 14 of tank or container 12.

It shall thus be recognized that when razor blade 36 is sulficientlyhoned by the oscillations of motor 28, switch 31) is then pushed to theoff position whereupon the arm 32 is lifted from within water 14 and therazor blade 36 disengaged from suction cups 34.

It shall further be noted that the arcuate glass 20 submerged withinwater 14 is removable from the top of plate 18 by urging it from beneaththe spring clips 22. A new glass 20 maybe placed in the same position,should the glass become broken, whereupon the sharpener may be placedinto operation again in the same manner as that heretofore described.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of theUnited States is:

1. A razor blade sharpener comprising, in combination, a hollow,rectangular container, said container providing reservoir storage forwater or other suitable solution for sharpening razor blades, arectangular magnet plate carried by said container providing a means forsecuring said container to a metallic surface to prevent moving of saidcontainer while in operation, an angular metallic plate carried withinsaid container providing resting means for an arcuately configuratedglass which provides means for honing a razor blade, a pair of springclips carried within said container providing means for securing saidglass within said container, an elongated arm and an elongated leafspring providing a means for holding said razor blade against saidglass, and a battery and motor housing carried by said containerproviding a means for housing electrical components of said sharpener.

2. The combination according to claim 1 wherein said container is filledwith water or other suitable solution to submerge said glass and saidrazor blade to be honed, and said glass is urged against said metalplate received within said water, and said metal plate is secured to anend wall and the base wall of said container to support said arcuatelyconfigurated glass, and said spring clips urge said glass against saidmetallic plate within said solution.

3. The combination according to claim 2 wherein said housing containingsaid batteries and said motor and associated mechanism is secured to anend wall adjacent said glass and said metallic plate received withinsaid container and switch means within the upper extremity of saidhousing secured to said end wall of said container provides a means forswitching said device on or oil.

4. The combination according to claim 3 wherein said elongated arm ispivotably secured within said housing of said device, and said arm isprovided with a pair of spaced apart suction cups at its lower extremityand said suction cups by means of difierential in pressure secure saidrazor blade to be sharpened to said arm and hold said razor blade whensaid arm is oscillated by said motor and said mechanism of said motor.

5. The combination according to claim 4 wherein the oscillating motionof said arm and said razor blade bones the edges of said razor bladebeneath said water or other solution within said container.
